| 摘 要： | 通过分析油蒿的生物生态学特性以及结合作者在库布齐沙漠东段对其的研究,文章认为油蒿的生态经济价值并没有先前想象的那么高。因为:(1)油蒿并不是固沙先锋植物。(2)油蒿通过化感作用和根系对水分的竞争抑制其他植物特别是深根系植物生长。(3)油蒿使土壤表层的紧实度、养分和有机质增加,利于浅根系植物生长。(4)多年生长的油蒿固定沙丘土壤水分不能得到有效补充,久而久之会引起油蒿大量死亡现象。(5)现阶段油蒿在生产沙蒿胶方面有一定的经济价值。

| Abstract: | With the analysis of biological and ecological characteristics of.4.ordosica and the study in the east of Kubqi desert,the author think that it has no excellent eco-economy value as respected.Because:1)It is not the pioneering sand binding plant;2) With the allelopathy and competition for water of its root,it can inhabit other plants especially deep root plants growing;3)It can increase compaction,nutrition and organic matter of surface soil,benefit to shallow root plants growing;4).4.ordosica will die seve... |
